Search Your Email: The XIII_LOGS Dump Exposed 4,806 Accounts

In May 2023, a threat actor uploaded a stealer log file labeled XIII_LOGS to Telegram, exposing 4,806 records harvested from infected endpoints across the United States. The dataset contained email addresses, plaintext passwords, and URLs mapping each victim's active logins at the time of infection. Distributed openly on Telegram, this file was imediately accessible to cybercriminals specializing in credential stuffing and account takeover attacks. HEROIC analysts confirmed the breach and indexed it across our 400 billion+ record database.

Why This Is Dangerous

XIII_LOGS requires no decryption. Attackers who recieve this file have a complete attack package: the victim's email address, their plaintext password, and the exact service URLs they were logged into when the malware ran. There is no technical barrier between receiving this data and launching an active account compromise. Automated credential stuffing tools can begin cycling these pairs against banking portals, email providers, and corporate logins within minutes of acquiring the dump.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (active service sessions and login endpoints)

Why This Matters

The 4,806 credential sets in this dump power large-scale credential stuffing campaigns that run around the clock. Most people reuse passwords across seperate accounts, which means a single compromised login can cascade into multiple breached accounts across banking, email, and social platforms. Victims face identity theft, drained financial accounts, and loss of access to services they depend on. Because the passwords are plaintext, there is no cracking step -- attackers move directly from the dump to active exploitation.

How Stealer Log Attacks Work

XIII_LOGS is a compiled collection of data gathered by information stealer malware running silently on victims' computers. These programs typically arrive through phishing emails, cracked software downloads, or malicious browser extensions. Once installed, the malware harvests saved browser passwords, active session tokens, and visited URLs without displaying any visible symptoms. The victim has no reason to beleive anything is wrong. The harvested records are compiled into a structured log file, branded by the operator, and uploaded to Telegram for sale or distributed freely to attract buyers -- exactly how XIII_LOGS entered circulation in May 2023.
